A real-time multipoint-based object detector - EMPDet is proposed in this paper to improve the processing speed with reasonable sacrifice in accuracy. A lightweight neural network block is proposed and integrated into the compact hourglass networks to reduce the consumption in image feature extraction. The channel mechanism is used to enhance the performance of the convolutional neural network to screen shallow semantic information in high-resolution feature maps. Experiments results on the detection benchmark (Microsoft COCO) show that the proposed detector has superior performance compared to the current most popular YOLOv3 under reasonable overhead.

Aiming at the problem that traditional traveling wave protection is difficult to take into account both quick-action and selectivity, an intelligent fault identification method for HVDC transmission lines based on S-transform multi-scale area is proposed. This method combines Radial Basis Function Network (RBFN) can accurately distinguish between internal and external faults, and at the same time achieve fault pole selection. First, the discrete S-transform is performed on the transient current signal, and multiple frequency scale signals are selected to calculate the area of the frequency signal after the fault. The S-transform multi-scale area is used to characterize the internal and external fault features and fault pole characteristics. The S-transform multi-scale area is used to form a feature vector, and the feature vector set is divided into a training set and a test set. The training set is trained to obtain an RBFN model, and the test set is used for testing. The prediction result obtained is the classification of different fault types. A large number of simulation results show that the method can effectively realize the internal and external fault identification and fault pole selection under different fault distances and different transition resistances, and has a strong ability to withstand transition resistances.

A negative selection algorithm based on adaptive immunoregulation 一种基于适应性免疫调节的负选择算法
Pub Date : 2020-06-01 DOI: 10.1109/ICCIA49625.2020.00041

Negative selection algorithm (NSA) is an important detectors training algorithm in artificial immune system (AIS). In NSAs, the self radius and location of detectors affect the performance of algorithms. However, the traditional NSAs preset the self radius empirically and generate detectors randomly without considering the distribution of antigens resulting in the performance of AIS varies greatly in different applications. To deal with these limitations, an adaptive immunoregulation based real value negative selection algorithm (AINSA) is proposed in this paper. AINSA utilizes the "adaptive immunoregulation" mechanism to calculate the self radius and optimize the location of the candidate detectors. In this way, AINSA can attain the suitable self radius for different application and effectively generate the detectors in the region where antigens distribute densely. The experimental results show, on the artificial dataset and the UCI standard datasets, AINSA can reach the higher detection rate with better detectors generation efficiency compared to the classical RNSA and V-detector algorithm.
负选择算法(NSA)是人工免疫系统中重要的检测器训练算法。在NSAs中,检测器的自半径和位置影响算法的性能。然而,传统的NSAs根据经验预设自身半径,随机生成检测器,而不考虑抗原的分布,导致不同应用中AIS的性能差异很大。针对这些局限性,本文提出了一种基于自适应免疫调节的实值负选择算法(AINSA)。AINSA利用“适应性免疫调节”机制计算自身半径并优化候选检测器的位置。这样,AINSA可以获得适合不同应用的自半径,并在抗原密集分布的区域有效地产生检测器。实验结果表明,在人工数据集和UCI标准数据集上,与经典的RNSA和V-detector算法相比,AINSA算法可以达到更高的检测率和更好的检测器生成效率。

Consumer purchase prediction is of great significance for reducing marketing costs and improving return on investment of companies. Recently, spatial-temporal data mining has aroused increasing concern. In this paper, we propose a hybrid deep learning model (EE-CNN) for purchase prediction, which combines entity embedding and convolutional neural networks. In empirical experiments, we first explore the purchase location pattern of different consumer groups on data sets from a retail company of China. After that, our proposed EE-CNN model is utilized to predict consumer purchase behavior. It turns out that location data can help improve the performance of purchase prediction models in general. Meanwhile, our proposed EE-CNN model outperforms baselines used in the experiments. Our research provides significant guidelines for the marketing decisions of enterprise marketers.

Electricity consumption reflects the development level of a certain region to a great extent, and it is always in a changing process with fluctuation. Entities or agencies who provide the electricity power supply services are always eager to know the data of regional electricity consumption, and hope to obtain the accurate forecast of future power consumption from these data, so that more appropriate and reasonable power supply service arrangement can be implemented. Till now, many scholars have reported their research on doing forecasting work by employing algorithms for regression such as Grey Theory or Random Forest, however, there are some drawbacks in both algorithms in using available data for prediction. In this paper, a short-term hybrid forecasting approach has been proposed based on both algorithms, it can not only realize the prediction from relatively less available data, but ensure high accuracy in prediction as well. By an empirical study on the electricity power consumption of a certain region in central western China, the effectiveness of the proposed method is verified.

People have relatively higher requirements for image storage in some specific fields, such as high-resolution cultural relic data image, medical image, infrared remote sensing image, high-precision astronomical observation image. There cannot be any pixel loss in the storage process, so the image can only be compressed by lossless compression. In this paper, a lossless image compression algorithm based on the neural network of long short-term memory (LSTM) is proposed: a LSTM model predictor based on attention mechanism is built by utilizing the memory characteristic of cyclic neural network. The previous pixel value of the image was taken as the input of the model, then the predicted pixel was obtained through the cyclic neural network, and finally the calculated difference between these values was encoded by the mixed run-length encoding and Golomb-Rice encoding. Compared with the traditional predictive lossless image compression algorithm, this algorithm proposed here comprehensively considers the correlation between more pixels and encoded pixels. The experimental results show that compared with the lossless image compression algorithms JPEG-LS and CALIC, the proposed algorithm improves the compression rate by 25% and 12% respectively.
在某些特定领域,人们对图像存储的要求相对较高,如高分辨率的文物数据图像、医学图像、红外遥感图像、高精度天文观测图像等。在存储过程中不能有任何像素损失,因此只能对图像进行无损压缩。提出了一种基于长短期记忆神经网络(LSTM)的无损图像压缩算法:利用循环神经网络的记忆特性,构建了一个基于注意机制的LSTM模型预测器。将图像先前的像素值作为模型的输入,然后通过循环神经网络获得预测像素,最后通过混合游程编码和Golomb-Rice编码对计算出的这些值之间的差进行编码。与传统的预测无损图像压缩算法相比,本文提出的算法全面考虑了更多像素与编码像素之间的相关性。实验结果表明,与无损图像压缩算法JPEG-LS和CALIC相比,所提算法的压缩率分别提高了25%和12%。

A novel particle swarm optimization with elite opposition-based learning algorithm is proposed in an attempt to improve the performance on solving large-scale optimization problems (LSOP) in maximum power point tracking (MPPT) of photovoltaic system. The standard particle swarm optimization (PSO) algorithm shows its weakness on LSOP, such as easily falling into local optimum, slow convergence and low accuracy at later evolution process. Therefore, this paper develops a modified PSO algorithm based on elite opposition-based learning mechanism and adaptive multi-context cooperatively coevolving (AM-CC) framework. In every iteration, the current high-priority individuals execute dynamic generalized opposition-based learning to generate their opposite solutions which enhance the ability of local exploration and help the particles escape from local optimum. The simulation experiments are conducted on a comprehensive set of benchmarks (up to 2000 real-valued variables), as well as on a large-scale MPPT application. Compared with some state-of-the-art variants of PSO and differential evolution (DE), the results show that the improved algorithm has higher convergence speed and accuracy. Besides, it can avoid premature phenomenon effectively and is suitable to solve the large-scale optimization problem.
为了提高光伏系统最大功率点跟踪(MPPT)中大规模优化问题(LSOP)的求解性能,提出了一种基于精英对立学习算法的粒子群优化算法。标准粒子群优化算法(PSO)在LSOP上表现出易陷入局部最优、后期进化过程收敛速度慢、精度低等缺点。为此,本文提出了一种基于精英对立学习机制和自适应多上下文协同进化(AM-CC)框架的改进粒子群算法。在每次迭代中,当前高优先级个体执行动态广义对立学习,生成它们的对立解,增强了粒子的局部探索能力,帮助粒子脱离局部最优。仿真实验是在一组全面的基准测试(多达2000个实值变量)以及大规模的MPPT应用程序上进行的。与现有的粒子群算法和差分进化算法相比,改进算法具有更高的收敛速度和精度。此外,它还能有效地避免过早现象,适用于解决大规模优化问题。

Automatic Fingerprint Extraction of Mobile APP Users in Network Traffic 基于网络流量的手机APP用户指纹自动提取
Pub Date : 2020-06-01 DOI: 10.1109/ICCIA49625.2020.00036

Network operators often need a clear visibility of the mobile APPs and their user scales running in the network traffic. This is critical for network management and network security. Analysis of the network traffic using the extracted APP features and user fingerprints is helpful for effective network operations, management, and security monitoring of LANs, MANs, and WANs. In China, the number of mobile APP users continues to increase, and the proportion of Internet users using mobile APPs to access the Internet far exceeds that of computers, making this task significant and difficult. The traditional methods are mainly APP identifications or identifications of specific APP users, which cannot satisfy the requirements of globally monitoring of APPs and their user scales at the same time. Especially when many users share the same network IPs (4G, home broadband, NAT), this work becomes challenging and time-consuming. This paper proposes an automatic fingerprint extraction approach of mobile APP users in network traffic. By analyzing the plaintext of the HTTP requests initiated by APPs in training datasets, we extract the APPs’ features and the users’ fingerprints simultaneously. Both of them are the combinations of strings which are distinguishable of APPs and their users in the network traffic. The proposed method is evaluated with the top 49 popular APPs in Huawei App Store. The experimental results show that the recalls of the extractions of APPs’ features and users’ fingerprints are respectively 77.5% and 55.1% in total.
网络运营商通常需要清楚地了解移动应用程序及其在网络流量中运行的用户规模。这对网络管理和网络安全至关重要。利用提取的APP特征和用户指纹对网络流量进行分析,有助于对局域网、城域网和广域网进行有效的网络运营、管理和安全监控。在中国,移动APP用户数量不断增加,使用移动APP上网的网民比例远远超过使用电脑上网的网民比例,这一任务意义重大,难度较大。传统的方法主要是对APP进行识别或对特定APP用户进行识别,无法满足同时对APP进行全球监测和用户规模监测的要求。特别是当许多用户共享相同的网络ip (4G、家庭宽带、NAT)时,这项工作变得具有挑战性和耗时。本文提出了一种基于网络流量的移动APP用户指纹自动提取方法。通过对训练数据集中app发起的HTTP请求的明文进行分析,同时提取app的特征和用户指纹。两者都是在网络流量中区分应用和用户的字符串组合。采用华为应用商店中排名前49位的热门应用对所提出的方法进行评估。实验结果表明,app特征提取和用户指纹提取的召回率分别为77.5%和55.1%。

This is critical for network management and network security. Analysis of the network traffic using the extracted APP features and user fingerprints is helpful for effective network operations, management, and security monitoring of LANs, MANs, and WANs. In China, the number of mobile APP users continues to increase, and the proportion of Internet users using mobile APPs to access the Internet far exceeds that of computers, making this task significant and difficult. The traditional methods are mainly APP identifications or identifications of specific APP users, which cannot satisfy the requirements of globally monitoring of APPs and their user scales at the same time. Especially when many users share the same network IPs (4G, home broadband, NAT), this work becomes challenging and time-consuming. This paper proposes an automatic fingerprint extraction approach of mobile APP users in network traffic. By analyzing the plaintext of the HTTP requests initiated by APPs in training datasets, we extract the APPs’ features and the users’ fingerprints simultaneously. Both of them are the combinations of strings which are distinguishable of APPs and their users in the network traffic. The proposed method is evaluated with the top 49 popular APPs in Huawei App Store. The experimental results show that the recalls of the extractions of APPs’ features and users’ fingerprints are respectively 77.5% and 55.1% in total.","PeriodicalId":237536,"journal":{"name":"2020 5th International Conference on Computational Intelligence and Applications (ICCIA)","volume":"78 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120821103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
